It is considered advisable to photograph each step when dis-assembling any mechanism. Have you contacted the mfr, or looked on their website for a service manual ?
They are only 15 dollars to buy new. With that in mind you could attempt to rebuild it but you need at least a micrometer to measure clearances. The pictures that I am looking at show a fiber retainer and a washer seal unit. You need to see if you can get those parts individually. The fiber washer may soften if you wet it and this would make it easier to insert it because the edge of the case appears tapered. However if you do that you need to be able to dry it in its original dimension.
